Question

Lance would like to lose two pounds a week. If his present energy intake is 4,200 kcal a day, his energy expenditure does not change, and 1 pound equals 3,500 kcals, how many kilocalories should he consume each day to achieve his goal?

a) 3200
b) 3600
c) 3800
d) 3400

Answer 1

a) 3200

Step-by-step explanation:

Total energy required to lose 2 pounds : 3500 x 2 = 7000

No. of days to lose energy = 7

Total energy required to lose per day : 7000/7 = 1000

So, Lance should take : 4200-1000 = 3200 kcal to lose 2 pounds in a week
